SPECIFICATION
Apparatus for imparting linear and rotary movement to a movable member This invention concerns apparatus for imparting linear and rotary movement to a movable member 70 and, although the invention is not so restricted, it is more particularly concerned with an industrial robot having a robot arm which can be rotated in the horizontal plane and can be raised and lowered.
A previously known industrial robot having such a robot arm effected rotation of the robot arm by means of a vertically extending tubular shaft which was mounted within a cylindrical portion of the fixed structure of the robot. This meant that each of the upper and lower ends of the tubular shaft needed to be supported by a bearing and that the tubular shaft itself needed to be of sturdy construction.
O The object of the present invention, however, is 85 to reduce the number of bearings which need to be employed and to simplify the construction so as to enable the apparatus to be made smaller and its cost to be reduced.
According therefore to the present invention 90 there is provided an apparatus comprising a movable member which is supported by fixed structure for linear movement and for rotational movement with respect to the fixed structure; first and second drive transmission members which are 95 drivingly connected to the movable member, the first drive transmission member being constituted by a cylindrical member which is mounted closely within a cylindrical portion of the fixed structure for linear and rotational movement therein, and 100 the second drive transmission member being mounted externally of the cylindral portion; first drive means connected to said first drive transmission member for imparting one said movement thereto; and second drive means having a part which is supported on and externally of the cylindrical portion, said second drive means being connected to the second drive transmission member for impErrting the other said movement thereto.
Preferably the said part is supported on the said cylindrical portion by way of a bearing, e.g. an anti-friction bearing such as a ball or roller bearing, or an air bearing.
so The first drive means is preferably arranged to 115 impart a linear movement to the first drive transmission member, the second drive means being arranged to impart a rotational movement to the second drive transmission member.
The linear movement is preferably vertical 120 movement, the rotational movement being rotation in the horizontal plane.
The said part which is supported on and externally of the cylindrical portion is preferably a rotary plate. In this case the second drive transmission member preferably extends freely through a hole in said rotary plate.
The rotary plate may be driven by an electric motor or may be driven by fluid actuated means.
The first drive means may comprise a screw and nut mechanism or alternatively may comprise fluid actuated drive means.
The present invention also comprises an industrial robot provided with apparatus as set forth above, the movable member being a frame which supports a robot arm.
The invention is illustrated, merely by way of example, in the accompanying drawings, in which:- Figure 1 (a) is a cross-sectional elevation of a known industrial robot, Figure 1 (b) is an horizontal cross-section of a portion of the structure shown in Figure 1 (a) and taken on the line D-D, Figure 2 is a cross-sectional elevation of a first embodiment of an industrial robot according to the present invention, and Figure 3 is a cross-sectional elevation of a second embodiment of an industrial robot according to the present invention.
Terms such as "upper" and "lower", as used in the description below, are to be understood to refer to directions as seen in the accompanying drawings.
In Figures 1 (a) and 1 (b) there is shown a known industrial robot which comprises fixed structure having a base portion 1, within which is provided a chamber 1 a bounded by an internal wall 1 b, and a vertically extending cylindrical portion 1 c. Mounted within the chamber 1 a is an electric motor 2 having a motor shaft 4 which extends freely through a hole 4a in the internal wall 1 b. The motor shaft 4 carries a pinion 3 which meshes with a gear 5a at the lower end of a vertically extending tubular shaft 5. The upper and lower ends of the tubular shaft 5 are rotatably supported within the cylindrical portion 1 c by respective bearings 6.
An electric motor 7, which is mounted within the chamber 1 a, has a motor shaft 8 which extends through a hole Ba in the internal wall 1 b. The motor shaft 8 is secured to a vertically extending feed screw 9 onto which there is threaded a non-rotatable nut 10. A rod 11, whose lower end is fixed to the internal wall 1 b, extends freely through a hole 1 Oa in the nut 10 so as to prevent the latter from rotating. Thus when the motor 7 effects rotation of the feed screw 9, the nut 10 is caused to travel vertically along the feed screw 9.
The nut 10 is provided adjacent its upper end with a recess or groove 1 Ob in which is rotatably mounted an end wall 12a of a cylindrical merber 12 which can thus be raised and lowered by operation of the motor 7. A pin 13 is mounted in a slot 12b in the cylindrical member 12, the pin 13 being secured by means of a nut 14 to the tubular shaft 5.
The external circumference 18 of the cylindrical member 12 is mounted closely within the internal circumference of the tubular shaft 5 so that the cylindrical member 12 is supported by the tubular shaft 5 for both rotational movement and linear vertical movement. As will be appreciated, when 2 GB 2 115 781 A 2 the motor 2 is operated, the tubular shaft 5 will be rotated and this rotation will be transmitted by way of the pin 13 to the cylindrical member 12. Thus the cylindrical member 12 can be angularly positioned by the motor 2 and vertically positioned by the motor 7.
The cylindrical member 12 is connected by bolts 16 to a frame 15 in which there is slidably mounted a robot arm 17 which is provided at one end with a manipulator (not shown).
Thus in the construction of Figures 1 (a) and 1 (b), two sets of bearings 6 had to be employed, which was expensive in view of the high degree of positional accuracy which needs to be given to the frame 15 and robot arm 17. These bearings 6, moreover, were highly loaded since they were subjected both to a moment load and to an axial load and it was necessary that both the bearings themselves and the other parts of the robot should be of sturdy construction so as to be able to withstand such loads. Consequently the power necessary to operate the robot was considerable.
Furthermore, it was difficult to place the arm 17 accurately in a desired position.
In Figure 2 there is therefore shown a first embodiment of an industrial robot according to the present invention having a fixed structure which comprises a base portion 20 and a cylindrical portion 20a, the base portion 20 being provided with an internal chamber 20b bounded by an internal wall 20c. Mounted within the chamber 20b is an electric motor 21 having a motor shaft 22 which extends freely through a hole 22a in the internal wall 20c. The motor shaft 22 is secured to the lower end of a vertically extending feed screw 23 onto which is threaded a non-rotatable feed nut 25. A vertically extending rod 24 whose lower end is fixed in the internal wall 20c extends freely through a hole 25a in the feed nut 25 so as to prevent the latter from rotating. Thus rotation of the feed screw 23 by the electric motor 21 produces vertical movement of the feed nut 2 5.
The feed nut 25 is provided adjacent its upper end with a groove or recess 25b within which there is rotatably mounted an end wall 26a of a cylindrical drive transmission member 26 which may thus be lifted and lowered by operation of the motor 2 1.
The cylindrical portion 20a of the fixed 115 structure is provided with an horizontal flange or plate 27 which is integral with the cylindrical portion 20a or is secured thereto. The horizontal plate 27 carries, by means not shown, an electric motor 28 having a motor shaft 30 which extends freely through a hole 27a in the plate 27. The motor shaft 30 is provided with a pinion 29 which meshes with a gear 31 a provided on a horizontally disposed rotary plate 31, The rotary plate 31 is supported on and externally of the cylindrical portion 20a by means of a mechanical bearing 37 which could be constituted by a journal bearing but which is preferably constituted by an anti friction bearing such as a ball or roller bearing.
The rotary plate 3 1 has a hole 3 1 b therein 130 through which freely extends a drive transmission rod 34 which is thus mounted externally of the cylindrical portion 20a. The drive transmission rod 34 is directly secured by a bolt or bolts 34a to a frame 32. The frame 32 is supported by the fixed structure 20, 20a for vertical linear movement and for rotational movement with respect thereto. The frame 32 is also directly secured to the upper end of the cylindrical drive transmission member 20 by means of bolts 33. Slidably mounted in the frame 32 is a robot arm 35 one end of which is provided with a manipulator (not shown). The frame 32 is thus supported by the fixed structure 20, 20a for linear movement and for rotational movement 80. with respect to the fixed structure, such linear movement being imparted to the frame 32 by the cylindrical drive transmission member 26, and such rotational movement being imparted to the frame 32 by the drive transmission rod 34.
The cylindrical drive transmission member 26 has an external cylindrical surface 36 which is mounted closely or journalled within the internal cylindrical surface of the cylindrical portion 20a so that the cylindrical drive transmission member 26 can be supported for linear and rotational movement within the cylindrical portion 20a.
In operation, when the electric motor 21 has been rotated by a preddermined amount in a predetermined direction, the feed screw 23 will be similarly rotated and the feed nut 25, which is prevented from rotating by the fixed rod 24, will move linearly vertically up or down by a predetermined amount in dependence upon the angular direction in which the motor 21 is driven.
Consequently, operation of the motor 21 will effect movement of the frame 32, and hence of the robot arm 35, linearly vertically.
When the motor 28 is rotated by a predetermined amount in a predetermined direction, the rotary plate 31 will be rotated through a predetermined angle about the cylindrical portion 20a. Consequently the frame 32, which is bolted to the drive transmission member 34, will be similarly rotated.
In the Figure 2 construction, the motors 21, 28 may be constituted by DC servo-motors and this enables the frame 32 to be stopped with high precision at any desired vertical or angular position. If, however, the frame 32 is to be stopped in only two different angular positions and only two different vertical positions, it is preferred to use the embodiment shown in Figure 3 which uses a pneumatic cylinder instead of the electric motor 21 and a pneumatic actuator instead of the electric motor 28.
In Figure 3 there is shown a second embodiment of an industrial robot according to the present invention having fixed structure which comprises a base 40 and a cylindrical portion 40a.
The base 40 has an internal chamber 40b within which there is mounted a pneumatic cylinder 41. Slidably mounted within the pneumatic cylinder 41 is piston 42a which is mounted at the lower end of a piston rod 42. The upper end of the piston rod 42 has flanges which define a recess 42b b- 3 GB 2 115 781 A 3 within which is rotatably mounted an end wall 43a of a cylindrical drive transmission member 43. Means (not shown) are provided for admitting compressed air to the cylinder 41 so as to move the cylinder rod 42 vertically therein and thus to raise and lower the cylindrical drive transmission member 43 so as to place the latter in either a predetermined upper position or a predetermined lower position. The cylindrical drive transmission member 43 has a cylindrical external surface 52 which is mounted closely or journalled within the internal cylindrical surface of the cylindrical portion 40a so that the cylindrical drive transmission member 43 is supported for rotation and for vertical sliding movement within the cylindrical portion 40a. The cylindrical drive transmission member 43 is bolted directly at its upper end to a frame 50 within which there is slidably mounted a horizontally extending robot arm 51 one end of which is provided with a manipulator (not shown).
The frame 50 is supported by the fixed structure 40, 40a for vertical linear movement and for rotational movement with respect to the fixed structure 40,40a.
The cylindrical portion 40a is integrally provided with a horizontal flange 45a to which is bolted an air actuator 44 by means of bolts 45.
The air actuator 44 is provided with pipes 46, 47 which communicate with air spaces within the air actuator 44 such that by supplying compressed air to one pipe and withdrawing it through the other, the air actuator 44 may be rotated between the two predetermined angular positions. The air actuator 44 is provided with a horizontally disposed rotary plate 48 which is supported on and externally of the cylindrical portion 40a. An air bearing 48b (or, alternatively, a mechanical bearing such as a ball or roller bearing) is provided between the rotary plate 48 and the cylindrical portion 40asoasto provide a rotatable mounting 105 for the latter.
The rotary plate 48 is provided with a hole 48a through which freely extends a drive transmission rod 49 which is bolted directly to the frame 50. The drive transmission rod 49 is thus mounted externally of the cylindrical position 40a.
Thus the frame 50, and hence the robot arm 51, may be moved vertically between two positions on operation of the air cylinder 41, and may be moved angularly in the horizontal plane between two positions by operation of the air actuator 44.
In the Figure 2 construction, both the cylindrical drive transmission member 26 and the drive transmission rod 34 are fixed directly to the frame 32. Similarly, in the Figure 3 construction the cylindrical drive transmission member 43 and the drive transmission rod 49 are fixed directly to the frame 50. This provides a more positive drive to the frame 50 than is possible in the prior art construction shown in Figure 1 in which only the cylindrical member 12 is secured directly to the frame 15.
The constructions shown in Figures 2 and 3 are simpler than that of Figure 1 and may be made smaller, with the result that the power required to drive the robot is therefore reduced.
